dnf facts

class reemote.facts.dnf.get_packages.Get_packages

Bases: object

Gets a list of installed DNF packages from a remote server.

This reemote operation executes dnf list installed on the target host to retrieve a list of all installed packages. It then parses the command’s output into a structured list of dictionaries.

The final result is stored in the stdout attribute of the completed process object returned by the operation.

Returns:

A list of dictionaries, where each dictionary

represents a package and contains ‘name’ and ‘version’ keys.

Return type:

list[dict]

Examples

# To be used within a reemote execution plan. The parsed
# list will be in the `stdout` of the result.
result = yield Get_packages()
packages = result.stdout

reemote.facts.dnf.get_packages.parse_dnf_list_installed(output)

Parses the output of the ‘dnf list installed’ command.

This function processes the raw string output from dnf list installed and converts it into a structured list of packages. It is designed to handle the specific format of the DNF command’s output.

Key transformations include:

• Skipping the header lines (e.g., “Installed Packages”).

• Correctly parsing lines where package names may contain spaces.

• Identifying the package name and version by working backward from the repository field, which is expected to start with an ‘@’ symbol.

Parameters:

output (str) – The raw string stdout from a dnf list installed command.

Returns:

A list of dictionaries, where each dictionary represents

an installed package and contains ‘name’ and ‘version’ keys.

Return type:

list[dict]
